Abstract: 3D-printing (also known as additive manufacturing) is a kind of growing processing method which can produce printed objects in a manner of "layer-by-layer stacking" by computer modeling. With the help of 3D printing technology, traditional porous materials such as zeolites can be processed into porous functional materials. The invention can break through the limitation of the traditional preparation method and be used to obtain functional materials with better practicability, better performance and wider usage. The research progress of integrated porous functional materials (3D-PFM) based on 3D printing technology was reviewed, and the preparation methods of 3D-PFM, including the selection of 3D-PFM printing process, the configuration of printing "ink" and the structure design of printing body, were described in detail. Major characteristics (porosity, acidity and compressive strength) of different 3D-PFMs were discussed. Besides, the applications of 3D-PFMs in the field of adsorption/separation and catalysis were briefly summarized. It was pointed out that in the future we should devote to the research and development of novel print consumables, focus on the development of in-situ functionalization strategy of integrated skeleton materials, focus on the structure-effect relationship of 3D-PFM, and strengthen the mechanism research in the process of preparation and application of 3D-PFM.
